The Institute of Contemporary Arts (ICA) is an artistic and cultural centre on The Mall in London, just off Trafalgar Square. Located within Nash House, part of Carlton House Terrace, near the Duke of York Steps and Admiralty Arch, the ICA contains galleries, a theatre, two cinemas, a bookshop and a bar.

Carlton House Terrace is a street in the St James's district of the City of Westminster in London. Its principal architectural feature is a pair of terraces, the Western and Eastern terraces, of white stucco-faced houses on the south side of the street, which overlook The Mall and St. James's Park. These terraces were built on Crown land between 1827 and 1832 to overall designs by John Nash, but with detailed input by other architects including Decimus Burton. Construction was overseen by James Pennethorne. Both terrace blocks are Grade I listed buildings. A separate but linked cul de sac at the terrrace's western end is named Carlton Gardens.
